The IARS provides a library of books and other publications of interest to amateur operators. The rules for borrowing from the library are as follows:. We are always on the look-out for new books to add to the club library.
To make a wireless link you will need at least 2 Moteinos. Alternatively this is compatible with other Arduinos that use any RFM69 transceiver. Here are a few features and highlights of Moteino:.
OMEGA was the first global-range radio navigation system, operated by the United States in cooperation with six partner nations. Taking a " fix " in any navigation system requires the determination of two measurements. Typically these are taken in relation to fixed objects like prominent landmarks or the known location of radio transmission towers.
Unfortunately at the time, the DOC would not allow a private repeater to be put on the air, it had to be done by an incorporated society. The purpose of this club would be to sponsor a repeater on Silver Star, teach amateur classes and to generate interest in electronics and radio in Vernon. Once again the reasons stated for forming the club included: 1.
Before delving into the mysteries of receiving and sending messages without wires, a word as to the history of the art and its present day applications may be of service. While popular interest in the subject has gone forward by leaps and bounds within the last two or three years, it has been a matter of scientific experiment for more than a quarter of a century. The wireless telegraph was invented by William Marconi, at Bologna, Italy, inand in his first experiments he sent dot and dash signals to a distance of or feet.
These services began in to permit citizens a radio band for personal communication e. There were two classes of CB: A and B. Class B radios had simpler technical requirements but were limited to a smaller range of frequencies.

Antenna tunermatching networkmatchboxtransmatchantenna tuning unit ATUantenna couplerand feedline coupler are all equivalent names for a device connected between a radio transmitter and its antennato improve power transfer between them by matching the specified load impedance of the radio to the combined input impedance of the feedline and the antenna. Antenna tuners are particularly important for use with transmitters. If the impedance seen by the transmitter departs from the design load, the output power of the transmitter can be reduced due to the failure to obtain a conjugate match.
